This is a sign of a broken module.
Request the author to use the kbuild infrastructure when building the module.
See Documentation/kbuild/modules.txt and Driver porting series at lwn.net for
good examples.

If you do not need CONFIG_MODVERSION then try to disable it and compile
the module, you may be lucky that it works.

But be carefull not to enable any options that may change ABI, for example reg-parm=3
is know to cause problems if not used consistently.
